@phkahler When looking into recent SVG export fixes I notice that this issue might be possible to address. I don't think we can make the construction style directly exportable. "export these objects" isn't available to change for the default styles. There is also no real way to "save" the construction style setting in the .slvs file since only custom styles are saved.

What we could do though is remove the explicit check that skips construction entities when exporting. We would also force the exportable flag to false for the construction default style (currently all default styles set export to true). This would preserve current behavior but If the user then restyled construction entities with a custom style that did have the export option enabled those entities would then export with the custom style.

it's not ideal and it is probably difficult for the user to discover but it should be simple to implement. It might be easier to demonstrate with a PR than to explain but I wanted your thoughts first.

I'm thinking the submitters idea 2 is the right thing to do since the option is already there but not working.

If exporting the built-in construction entities is desired, we can talk about weather that's a global option or a checkbox per style or something else. What do you think @robnee and @gnbl ?

I should have reread the OP. Idea 2 is essentially what I was suggesting. In fact I tried it and it works as expected. It's a simple change but it's not very discoverable. This is a per-file option (it's already part of the .slvs format) and the ability to have multiple custom styles for different construction entities makes it very flexible.

The configuration already has a number of export options so it might make sense to have another for "export construction entities". It's more discoverable and wouldn't require the user to restyle their construction entities. Maybe "export construction entities in 2D" or similar helps indicate for which exports it will apply. This option applies globally so is simple but less flexible.

I am happy with either approach really.

Any kind of option to allow this would be appreciated, so whatever is easiest to implement.
Thanks!

Finally got around to testing (3.0~53f5e4e7 Windows OpenMP) - awesome, thanks!

I've noticed two related things:

• can't export light gray construction geometry to PDF (output appears identical with 0.1 or 0.9 brightness, minor difference to black visible with 0.2)
• "line styles" > "load factory defaults" could automatically do a redraw

Let me know if you want two separate issues.

I'll look at automatically refreshing if resetting the styles. Is "Fix white lines on export" checked? That will draw light colors as black on export. Try turning that off to export light grey.

Yes, that was it. Thought it was to be taken literally. Thanks.

Ah but then actual construction geometry edges (active-grp) are exported white. Easily fixed by choosing a dark color before exporting. For frequent use a bit of a hassle - could the "fix light lines on export" option be per line-style as well? Or rather inherit the global option as is, but allow deselection for specific styles.
Sorry, just an idea.

That would affect the .slvs file format and would probably not get merged for backwards compatibility reasons. The lightest gray that will export without being changed to black is approx (0.77, 0.77, 0.77) as determined by:

sqrt((1-r)^2 + (1-g)^2 + (1-b)^2) < 0.4

Does that work for your purposes?

Thanks for taking the time to look into it. I'll give it a try. Meanwhile I've noticed that the default green for construction geometry isn't too bad after conversion to grayscale (for print).
Cheers!
